Abstract
THE surface helium abundance of stars at the blue end of the horizontal branch in globular clusters and of halo B stars has been estimated by spectroscopists to be lower than that at the Sun's surface by factors ranging from 10 (refs. 1 and 2) to 100 (ref. 3). It is assumed that the halo B stars are the field-equivalents of horizontal branch stars, and we hereafter refer to both classes as blue horizontal branch stars.
